+# Why would I have to... switch ?
+Almost 99% of Minecraft servers use Aikar's Flags and it is recommended by many people (some use nothing !). But why use other flags ?
+The answer is that we have now developed to Minecraft 1.21.x and Java 22 (at the time of writing this) and Aikar's Flags **was written mainly to optimize Minecraft's Garbage Collector** and Java at that time (around 2018 - 2020). Later Java versions (from Java 17 and above) have added many optimization items for JVM. So I wrote a separate flag to support optimizations and integrates new features of Java 17+ while still keeping Aikar's flags to optimize GC. <ins>There's no risk in trying my flags !</ins>
